GAS-CONTROLIJ-ING APPARTS.

Application filed April 22, 1910. Serial No. 557.043.

lil/ly invention relates to improvements in gas-controllingapparatus,and my object is to r'ivitle newl and novel apparatus Whereby the supplyof gas or 'other liuid entering a building through the service-pipethereof, may be readily out ofi in luse of fire, or at any other timedesired.

The apparatus embodies a self-closing velye for controlling the flow offluid through the service-rupe, manually-operable ineens whereby saidvalve may be controlled at 'a point distantI therefrom, 'and fusibleincanswhich when subjected to a predetermined degree of heat will meltand permit the valve to automatically close,

ln order that the invention may b'e fully understood, reference Will nowbe made to the accompanying drawings in which: l

Fiagure l is i side elevation partly in section of iny improvedapparatus. Fig. 2 is n detail vertical section on line H-ll of l.r Fig.3 is a section on line IIL-HI 2, with a portion of a conduit added. is aCentral vertical section ot' the uw.: on line .iV-lV of l.

l designates a service-pipe for conducting Afluid from the main (notshown) into a building, the iront wall Qvof which only is Shown.

3 designates a valve for controlling the How oi fluid into the buildingthrough the service-pipe l. baid val ve consists ot" a shell il; havinga port 5 for the 1'nxssuge of the liu i x sliding-gate (S for closing'said port.

Yseat 18 clean ot any is provided at its lower end with tubular guidel0, closed by a screw-cap ll, and adapted `to receive 'the lower cudstem 7 as the saine approaches the end ward stroke. rlhe upper portionet has a stutlingbox l2 through which the stein 7 extends and. saidupper portion has. riso, a pair oi oppositely-extendingr.diametrically-opposed arms to carry a bracket 1L. Gate 6 is providedwith lug; proviecting therefrom and having a beveled side lo lforengaging a correspon-dir beveled portion 17 of the stein which n lievalve cloaes pushes the gate firmly :n iinst it.V rat l5. thevalve-sten@ being breve t inde lltrom springing baci; onder the r "ureexerted by its beveled portion l might interfere 'with I gate.

' f and.

`7 bracket upon arnls lil smid bracket may he turned to face the tubulnrextensions in` almost any direction. 'to receive the lower ends of apair ot conduits 325,

34; designates a nut having a thread 35 extending' into a spiral .Groovein the uilper enlarged portion or stein 7. to actuele said stem as\\ill'l1e1einafter appear.

3l isconnected by o fusible substance l to the hub 37 ol asprocket-wheel 35%,. which extends between the diametricallybpnosedbifurcated portions L. und i ald thereby from xf'ertical n'wrcmc t 'l:ich the Nut vided with a handle 45 whereby it and the conduits' 33, andattached at their adapted to abut against a staple '53er a' upper endsto a similartape 43 extending halt-way around a sprocket-wheel 44,'Apromay be actuated. Sprocket-wheel 44' is mounted-v upon a Ashaft 46 journaled in a box 47 pro-` vided. with a hinged door 48, so thataccess,l

may be had'to the handle 45 `forthe purpose of turning sprocket-Wheel 38to manually,

close the valve. Door 48 is provided with a staple 49 to receive theslotted end of a hasp 5G loosely secured to theuppr side of 'the box, sothat its` slottednd may be placed in position over staple 49, and secured by a padlock 5 1, to prevent irrespon-y :sible persons fron'igaining access to handle scrlbed, a'f'se'rviee-pipe 'for conductingfluid y4 5 to tamper with the same. Tamp'ering, with handle-'45, isfurther guarded' against by providing the saine withfa Astaple 52"staple 54 in the box, and be locked in engagement therewith by apadlock 55. Door 48 has grooves 56 therein, to weaken the' same, sothat; access, may be readily `had-to handle infcasebf door, after whicheither of the staples thioughavhich the hasp of lock 55 extends, maybe'brolcen to 'release the handle '45. Sprocket-wheel 441` is 'ofgreater diameter than sprocket-wheel 38, so that the latter will beturned one revolution by turning the iornier about t\vo-th1rds of 'arevolution, or

suiiiciently to swing handle '45 from staple 52 to staple 54, as onerevolution of sprocket-` wheel 38 is neccssary'to close valve 3v .whenthe parts are made in about the proportions shown in the drawings. l

Cables 42 which consist preferablyof fire- 'fprooi' material are furtherprotected r`bythe conduits 33, which latter have adjustable elbows 57 sothat they may be extended lin any desired direction. Elbows 57 consistofadjustable ,sections 58 and 59, which are pivotally connected by bolts60, carrying grcoved rollers v6l to guide the cables 42 through thenconduits.

In practice, the valve is held in the open' position shown in Fig. l bynut 34. Should a fire occur in the building, or should it be desirablefor any reason to cut-oit' the flow.

el u'id through the service-pipe 1, any au'- thorizcd person canpromptly perform this operation by opening the box 47, lgrasping handle45, and swinging -it around until stopped bythe staple 54. This movementof the handle rotates wheel 38 and causes i1- thr'gh the intermedi-cy l4 Parts 2 death@ valve. 'Should ai@ fusibie :would nut 34 `fromwheell38, and .permitspri'ng 8,' lever19, and weight 20 tov voriginal pa fire by breaking saidj v1,033,9ise

thus automatically close the valve. After the yfire had .beenextinguished4 and the fusible substance -36 bet-Ween nut 34 and wheel 38hadr been renewed, the valve could lbe opened bymoving handle 45 back toits 'osition or until its Staple 52 contacted with staple 53. l WVhileI, have shown-the preferred form ro'f my invention, I, of course, 'donotllirhit .myself tothe exact construction and arrangementfof parts asshown and described, as it is obvious that changes can be made withoutdeparting from the spirit or scope ofl the appended claims.

` Having thus described my invention, what I I claim is:kv :p

1. -In an apparatus ofthe character deintol a` building, a valve tocontrol the flow' lf-fluidthroughsaidpipe, a Wheel on said 'valve toopenand close the same, means extending' at'a distance from' said wheel forturning the same in either direetiom conduits for. protecting saidmeans, and a bracket adjustably-secured tothe valve, said 'bracketVhaving tubular portions to communicate with ,the oonduitsand bifurcatedportions to prevent lateral movement of the wheel.

*12. In an apparatus ofjthevcharactcr de# scribed, a service-pipe forconducting iluid into a building, a valve tocontrol'the flow 'ofiluidthrough said pipe, manually-operable means extending ata distance from:said'valve to close the same, a'box inclosing that portion of saidmeans most remote' from the valve, said box havin-g a grooved nreakableportion, and means for 'locking said box in closed position;

3. In an apparatus of the character described, a service-'pipe .forconducting fluid into a building, a valve to control the`,ilo;1sr

vrof fluid `'through said pipe, said'valve having a spiral groove, a nutengaging the groovedportion of said valve to open or close the same, awheel for actuating said nut, and a bracketfloosely engaging oppositesides ofsaid wheel to prevent the same from moving in any other than Aarotary direction.

In` testimony whereof I aiiix my signature, in the presence ot twowitnesses.
